In 1807, three years after Lewis and
Clark first noted the presence of a salt lick in the
area, Nathan and Daniel Boone (sons of the pioneer Daniel
Boone) blazed a trail from Saint Charles to a point
just northwest of present day Boonville. The road terminated
at the Boones' salt lick. A few years later, there was
a movement to make the trail a wagon road and in 1827
this was done. The salt lick was used up until 1833;
a state historic site now preserve's the Boones' small
settlement.
